I am casting these emblems (see below) and I am trying to come up with a time effective way of sanding the face in preparation for polishing. Currently, for the sample parts, I am simply sanding them with sand paper on a flat steel table. Works well but is very time consuming. It's quite important that the face be sanded as flat as possible with very minimal "diving off" of the the sharp corners.
So, I am looking for a powered alternative. I have been considering a belt sander, or one of
those rubber expander wheels
The sanding belt has the draw back of how to hold onto the part while sanding. The part is only .170 thick.
Do you think the expander wheel, with the proper technique is capable of not rippling the surface?
Any other suggestions?
